29 CFR
Electricity is essential to modern life, both at home and on the job. Some employees engineers, electricians, electronic technicians, and power line workers, among them work with electricity directly. Others, such as office workers and sales people, work
with it indirectly. Perhaps because it has become such a familiar part of our daily life, many of us don’t give much thought to how much our work depends on a
reliable source of electricity. More importantly, we tend to overlook the hazards electricity poses and fail to treat it with the respect it deserves.

4. Introduction
An average of one worker is electrocuted on the job every day
There are four main types of electrical injuries:
Electrocution (death due to electrical shock)
Electrical shock
Burns
Falls
Electricity has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires, and
explosions. In 1999, for example, 278 workers died from electrocutions at work, accounting for almost 5 percent of all on-the-job fatalities that year, according to the Bureau of Labor Statistics. What makes these statistics more tragic is that most of these fatalities could have been easily avoided.

5. OSHA Standards
Electrical safety-related work practice requirements for general industry are detailed in Subpart S of 29 CFR
Part 1910, in Sections – For
construction applications, electrical safety-related
work practice requirements are detailed in
Subpart K of 29 CFR Part to
OSHA standards focus on the design and use of electrical equipment and systems. The standards cover only the exposed or operating elements of an electrical installation such as lighting, equipment, motors, machines, appliances, switches, controls, and enclosures, requiring that they be
constructed and installed to minimize workplace electrical dangers. Also, the standards require that certain approved testing organizations test and certify electrical equipment before use in the workplace to ensure it is safe.

6. Electric Basics Electrical Flow:
Conductors – substances, such as metals- little resistance to electricity
Insulators – substances, such as wood, rubber, glass, and bakelite-high resistance to electricity
Current – the movement of electrical charge
Resistance – opposition to current flow
Voltage – a measure of electrical force
Grounding – a conductive connection to the earth which acts as a protective measure
Electricity flows more easily through some materials than others. Some substances such as metals generally offer very little resistance to the flow of electric current and are called “conductors.” A common but perhaps overlooked conductor is the surface or subsurface of the earth. Glass, plastic, porcelain, clay, pottery, dry wood, and similar substances generally slow or stop the flow of electricity. They are called “insulators.” Even air, normally an insulator, can become a conductor, as occurs during an arc or lightning stroke.
Operating an electric switch is like turning on a water faucet. Behind the faucet or switch there must be a source of water or electricity with something to transport it, and with a force to make it flow. In the case of water, the source is a reservoir or pumping station; the transportation is through pipes; and the force to make it flow is provided by a pump. For electricity, the source is the power generating station; current travels through electric conductors (wires); and the force to make it flow - voltage, measured in volts, is provided by a generator.
Resistance
- Dry skin has a fairly high resistance, but when moist, resistance drops radically, making it a ready conductor.
- Measured in ohms.
Use extra caution when working with electricity when water is present in the environment or on the skin. Pure water is a poor conductor, but small amounts of impurities, such as salt and acid (both are contained in perspiration), make it a ready conductor.

7. Electricity Basics Water and electricity
Pure water is a poor conductor
Impurities can make water an insulator
Salts
Acid
Solvents
Working in a damp environment requires preventive measures against electrical hazards
Pure water is a poor conductor. But small amounts of impurities in water like salt, acid, solvents, or other materials can turn water itself and substances that generally act as insulators into conductors or better conductors. Dry wood, for example, generally slows or stops the flow of electricity. But when saturated with water, wood turns into a conductor. The same is true of human skin. Dry skin has a fairly high resistance to electric current. But when skin is moist or wet, it acts as a conductor. This means that anyone working with electricity in a damp or wet environment needs to exercise extra caution to prevent electrical hazards.

8. Electric Basics What causes shocks?
Electricity travels in closed circuits, usually through a conductor
Your body can be a conductor which may mean an electrical shock!
Electricity travels in closed circuits, normally through a conductor. But sometimes a person’s body — an efficient conductor of electricity — mistakenly becomes part of the 6 electric circuit. This can cause an electrical shock. Shocks occur when a person’s body completes the current path with:
• Both wires of an electric circuit
• One wire of an energized circuit and the ground
• A metal part that accidentally becomes energized due, for example, to a break in its insulation
• Another “conductor” that is carrying a current
When a person receives a shock, electricity flows between parts of the body or through the body to a ground or the earth.
What effect do shocks have on the body?
An electric shock can result in anything from a slight tingling sensation to immediate cardiac
arrest. The severity depends on the following:
• The amount of current flowing through the body
• The current’s path through the body
• The length of time the body remains in the circuit
• The current’s frequency
Copyright ã1999 Business & Legal Reports, Inc.

9. Electrical Shock Current passes through the body
Severity of the shock depends on:
Path of current through the body
Amount of current flowing through the body
Length of time the body is in the circuit
Low voltage does not mean low hazard

10. Types of Electrical Shock Injuries
Electrical burns
Thermal contact burns
Related hazards:
Fire
Equipment damage
Fragmented metal
Flammable gases, vapors or combustible dusts
Arc or flash burns
Burns are the most common shock-related injury. An electrical accident can result in an electrical burn, arc burn, thermal contact burn, or a combination of burns.
Electrical burns are among the most serious burns and require immediate medical attention. They occur when electric current flows through tissues or bone, generating heat that causes tissue damage.
Arc or flash burns result from high temperatures caused by an electric arc or explosion near the body. These burns should be treated promptly.
Thermal contact burns are caused when the skin touches hot surfaces of overheated electric
conductors, conduits, or other energized equipment. Thermal burns also can be caused when clothing catches on fire, as may occur when an electric arc is produced.
In addition to shock and burn hazards, electricity poses other dangers. For example, arcs that result from short circuits can cause injury or start a fire. Extremely high-energy arcs can damage equipment, causing fragmented metal to fly in all directions. Even low-energy arcs can cause violent explosions in atmospheres that contain flammable gases, vapors, or combustible dusts.

12. “Freeze” Electrical shock may cause the muscles to contract
This “freezing: effect” is dangerous
Increases the length of exposure
If you witness a “freeze”
Shut off the power
Use a non-conductive object to knock the person free of the contact
When a person receives an electrical shock, sometimes the electrical stimulation causes the muscles to contract. This “freezing” effect makes the person unable to pull free of the circuit. It is extremely dangerous because it increases the length of exposure to electricity and because the current causes blisters, which reduce the body’s resistance and increases the current.
The longer the exposure, the greater the risk of serious injury. Longer exposures at even relatively low voltages can be just as dangerous as short exposures at higher voltages. Low voltage does not imply low hazard.
In addition to muscle contractions that cause “freezing,” electrical shocks also can cause involuntary muscle reactions. These reactions can result in a wide range of other injuries from collisions or falls, including bruises, bone fractures, and even death.
If a person is “frozen” to a live electrical contact, shut off the current immediately. If this is not possible, use boards, poles, or sticks made of wood or any other non-conducting materials and safely push or pull the person away from the contact. It’s important to act quickly, but remember to protect yourself as well from electrocution or shock.

13. Severe Shock A severe shock requires medical help immediately
Unseen medical issues may be present, such as:
Internal Hemorrhages
Destruction of tissues, nerves
or muscles
A severe shock can cause considerably more damage than meets the eye. A victim may suffer internal hemorrhages and destruction of tissues, nerves, and muscles that aren’t readily visible. Renal damage also can occur. If you or a coworker receives a shock, seek emergency medical help immediately.

14. Static Electricity Created when materials rub together
Can cause shocks or even minor skin burns
Reduced or prevented by:
Proper grounding
Rubber matting
Grounding wires, gloves, or shoes
Static electricity is very common in the workplace and at home. It is caused when two materials rub against each another and build up a charge of electricity. The static is finally dissipated when a grounded conductor, such as a doorknob, is touched.
Sometimes static electricity can result in arcs of electricity leaping from a person onto an operator’s metal console. This type of static electricity can cause minor skin burns. It can cause dangerous shocks for people with heart conditions.
Static electricity can be reduced by properly grounding the equipment, providing rubber matting (i.e., increased resistance) for the operator to stand on, or providing PPE such as grounding wires that connect to a worker’s wrist, gloves, or shoes.

15. Protection Against Electrical Hazards
Insulation
Guarding
Most electrical accidents result from one of the following three factors:
• unsafe equipment or installation
• unsafe environment
• unsafe work practices
Some ways to prevent these accidents are through the use of insulation, guarding, grounding, electrical protective devices, and safe work practices.
Insulators such as glass, mica, rubber, or plastic used to coat metals and other conductors help stop or reduce the flow of electrical current. This helps prevent shock, fires, and short circuits. To be effective, the insulation must be suitable for the voltage used and conditions such as temperature and other environmental factors like moisture, oil, gasoline, corrosive fumes, or other substances that could cause the insulator to fail.
Identifying types of insulation: Insulation on conductors is often color coded. Insulated equipment grounding conductors usually are either solid green or green with yellow stripes. Insulation covering grounded conductors is generally white or gray. Ungrounded conductors, or “hot wires,” often are black or red, although they may be any color other than green, white, or gray. Before connecting electrical equipment to a power source, it’s a good idea to check the insulation for any exposed wires for possible defects. Insulation covering flexible cords such as extension cords is particularly vulnerable to damage.
Guarding involves locating or enclosing electric equipment to make sure people don’t accidentally come into contact with its live parts. Effective guarding requires equipment with exposed parts operating at 50 volts or more to be placed where it is accessible only to authorized people qualified to work with it. Recommended locations are a room, vault, or similar enclosure; a balcony, gallery, or elevated platform; or a site elevated 8 feet (2.44 meters) or more above the floor. Sturdy, permanent screens also can serve as effective guards.
Conspicuous signs must be posted at the entrances to electrical rooms and similarly guarded locations to alert people to the electrical hazard and to forbid entry to unauthorized people. Signs may contain the word “Danger,” “Warning,” or “Caution,” and beneath that, appropriate concise wording that alerts people to the hazard.

16. Grounding
Most electrical equipment is designed with a grounding system
Do not use equipment with damaged grounding connectors
Do not use adapters that interrupt the grounding connection
“Grounding” a tool or electrical system means intentionally creating a low-resistance path that connects to the earth. This prevents the buildup of voltages that could cause an electrical accident. Grounding is normally a secondary protective measure to protect against electric shock. It does not guarantee that you won’t get a shock or be injured or killed by an electrical current.
A service or system ground is designed primarily to protect machines, tools, and insulation against damage. One wire, called the “neutral” or “grounded” conductor, is grounded. In an ordinary low-voltage circuit, the white
or gray wire is grounded at the generator or transformer and at the building’s service entrance.
An equipment ground helps protect the equipment operator. It furnishes a second path for the current to pass through from the tool or machine to the ground. This additional ground safeguards the operator if a malfunction causes the tool’s metal frame to become energized. The resulting flow of current may activate the circuit protection devices.
Circuit protection devices limit or stop the flow of current automatically in the event of a ground fault, overload, or short circuit in the wiring system. Well-known examples of these devices are fuses, circuit breakers, ground-fault circuit interrupters, and arc-fault circuit interrupters.
Fuses and circuit breakers open or break the circuit automatically when too much current flows through them. When that happens, fuses melt and circuit breakers trip the circuit open. Fuses and circuit breakers are designed to protect conductors and equipment. They prevent wires and other components from overheating and open the circuit when there is a risk of a ground fault.
Arc-fault devices provide protection from the effects of arc-faults by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when an arc-fault is detected.
Almost all electrical equipment is designed with some sort of grounding system so that if there is a problem such as a short circuit, the electrical current will go to ground through the grounding system rather than through the human body.
Do not use equipment with damaged grounding connectors. Some people might alter a 3-prong plug by cutting off the grounding prong so that they can plug into a 2-prong receptacle. This practice is not safe because you are bypassing an equipment safeguard and setting yourself up for an injury.
Another option is to use an adapter that converts a 3-prong system into a 2-prong system. Again, this interrupts the grounding connection. The adapters are not designed to send the current to ground if there is a problem.

17. Grounding Fault Circuit Interrupters
GFCIs reduce the likelihood of fatal shocks
Detect small amount of earth current and automatically switch off the power
Used with extension cords and portable tools
Fuses and circuit breakers protect equipment, not people
Ground-fault circuit interrupters, or GFCIs, are used in wet locations, construction sites, and other high-risk areas. These devices interrupt the flow of electricity within as little as 1/40 of a second to prevent electrocution.
GFCIs reduce the likelihood of fatal shocks by automatically switching off the power when a small amount of earth or grounded current is detected.
GFCI receptacles might be found in homes or hotels in the bathroom or kitchen where an electric appliance such as a hair dryer or toaster has a chance to fall into a sink full of water. If this occurred, the GFCI would automatically shut off the power to the receptacle. The receptacle would have to be manually reset.
GFCIs can also be portable and used with extension cords and power tools.
Fuses and circuit breakers operate at several Amps to allow the circuit to continue even when slightly overloaded. Remember, people are injured at the milliAmp level.
Copyright ã1999 Business & Legal Reports, Inc.

18. Circuit Protection
Energize or de-energize with appropriate switches, breakers, etc.
Do not energize or de-energize with fuses, terminal lugs, or cable splice connections
If circuit protection device is tripped—inspect
Circuits are protected with equipment such as breakers or fuses. These allow a certain amount of amperage in the circuit before blowing, tripping, or otherwise breaking the circuit. They are used to protect equipment and wiring in the system from being damaged by too much electrical current.
Energize (close the circuit) or de-energize (open the circuit) with the appropriate equipment such as switches or breakers.
Do not open or close circuits by installing and removing fuses, taking terminal lugs off and on, or by splicing cables.
If a circuit protection device is tripped, have an authorized worker inspect the system before manually re-energizing the circuit. There may be a short or some other electrical hazard that needs to be repaired.
Copyright ã1999 Business & Legal Reports, Inc.

19. Protection from Power Lines
Maintain a safe distance to the lines High-voltage lines
Ground any equipment such as cranes that can become energized
Lines must be de-energized and grounded by the owner or operator of the lines
Guarding or insulating the lines help prevent accidental contact
OSHA E-Tool:
Before working under or near overhead power lines, ensure that you maintain a safe distance to the lines and, for very high-voltage lines, ground any equipment such as cranes that can become energized. If working on power lines, ensure that the lines have been de-energized and grounded by the owner or operator of the lines. Other protective measures like guarding or insulating the lines help prevent accidental contact.
Employees unqualified to work with electricity, as well as mechanical equipment, should remain at least 10 feet (3.05 meters) away from overhead power lines. If the voltage is more than 50,000 volts, the clearance increases by 4 inches (10 centimeters) for each additional 10,000 volts.
When mechanical equipment is operated near overhead lines, employees standing on the ground should avoid contact with the equipment unless it is located outside the danger zone. When factoring the safe standoff distance, be sure to consider the equipment’s maximum reach.
Copyright ã1999 Business & Legal Reports, Inc.

20. Protection for Machine Operators
Never tamper with electrical interlocks
Do not repair electrical components of your machine
Properly shut off machinery before working in the point of operation
Obey warning signs and follow safe procedures
Never tamper with or bypass electrical interlocks or other machine safeguards. You are risking injury to yourself and others every time you do this.
Do not attempt to repair electrical components of your machine. Do not even open your machine’s electrical panel. Remember, only authorized workers are permitted to repair or work on electrical equipment.
Properly disengage or shut off your machine before working in its point of operation. This may mean hitting the emergency stop or even calling an authorized worker to lock out the machine first.
Obey warning signs and stickers, particularly those that warn of high voltage.
Learn to identify electrical malfunctions of your machine.
Copyright ã1999 Business & Legal Reports, Inc.

21. Protection Against Energized Metal Parts
A break in an electric tool’s or machine’s insulation can cause its metal parts to become “hot”
Use “double insulated” tools
Equipment grounding conductor such as a three prong plug
A break in an electric tool’s or machine’s insulation can cause its metal parts to become “hot” or energized, meaning that they conduct electricity. Touching these energized parts can result in an electrical shock, burn, or electrocution. The best way to protect yourself when using electrical tools or machines is to establish a low-resistance path from the device’s metallic case to the ground. This requires an equipment grounding conductor, a low-resistance wire that directs unwanted current directly to the ground. A properly installed grounding conductor has a low resistance to ground and greatly reduces the amount of current that passes through your body. Cord and plug equipment with a three-prong plug is a common example of equipment incorporating this ground conductor.
Another form of protection is to use listed or labeled portable tools and appliances protected by an approved system of double insulation or its equivalent. Where such a system is employed, it must be marked distinctively to indicate that the tool or appliance uses an approved double insulation system.

22. Unexpected Equipment Startup
Proper lockout/tagout procedures protect from dangers of accidental startup of electrical equipment
29 CFR , Lockout and Tagging of Circuits
The first step before beginning any inspection or repair job is to turn the current off at the switch box and padlock the switch in the OFF position. This applies even on so-called low-voltage circuits. Securely tagging the switch or controls of the machine or equipment being locked out of service clarifies to everyone in the area which equipment or circuits are being inspected or repaired. Only qualified electricians who have been trained in safe
lockout procedures should maintain electrical equipment. No two of the locks used should match, and each key should fit just one lock. In addition, one individual lock and key should be issued to each maintenance worker authorized to lock out and tag the equipment. All employees who repair a given piece of equipment should lock out its switch with an individual lock. Only authorized workers should be permitted to remove it.
Copyright ã1999 Business & Legal Reports, Inc.

23. Lock Out Tag out: Lightning in a Bottle Video
Fatal injuries occur when hazardous energy is released and safety precautions are not in place. Never allow that to happen. Bottle up that uncontrolled energy, train your employees and boost your lockout/tagout measures with this shockproof program.

24. Portable Power Tools Safety
Inspect portable power tools
Never use damaged equipment
Tag it out of service
Have it repaired or replaced
Never use portable power equipment in wet or damp areas
Stop using power tools if they become hot or start sparking
DEMO: Bring a portable power tool to the class so that you can point out the different hazards to the employees.
Portable power tools are used by almost everyone either at work or at home. They need to be taken care of and properly inspected because they can have many of the potential hazards listed on the previous slide such as:
Damaged wire insulation
Broken plugs
Overloaded circuits (i.e., pop a fuse when turned on)
Overheated or sparked
If you find that a power tool is damaged, tag it out of service and have it repaired or replaced.
Using portable power tools in a wet or damp area is just asking for the electricity to go to ground and shock you.
If a power tool appears to be getting too hot or starts sparking, stop using it, tag it out of service, and have it repaired or replaced.
Copyright ã1999 Business & Legal Reports, Inc.

25. Extension Cords Inspect and check for capacity For temporary work only
Do not use as a rope to pull or lift objects
Should not be fastened with staples or hung over hooks
Extension cords can also have some of the general hazards listed in the earlier slide, so they should always be inspected before use.
Also make sure the cord is rated for the load you plan to put on it. Can that extension cord handle the 15 strings of Christmas lights and the illuminated snowman with the waving arm? Is the extension cord rated for outdoor use? If not, the cord could become overheated, start a fire, or blow a circuit breaker in your home.
Extension cords are designed for temporary work. They are not intended to be used as a permanent power source because they are more likely to be damaged or overloaded, and they are not supplied with their own circuit breaker as a hardwired system would be.
Extension cords are not ropes. They can easily be stretched and damaged if used to hoist objects.
Do not use staples or nails to hang extension cords because this could cause damage to the outer jacket of insulation. If the wire were to become exposed, the current could reach ground through the nail or staple and cause a short-circuited and hot cord.
Copyright ã1999 Business & Legal Reports, Inc.

26. Electrical Cord Inspection
Deformed or mission pins
Damaged outer jacket or insulation
Evidence of internal damage
If damaged, take out of service until repaired
Inspect the plugs for deformed or missing pins. Don’t yank an electrical cord out of the socket by pulling on the cord. Remove the cord by pulling on the plug.
Inspect the outer jacket or insulation of the cord for cuts, abrasions, or signs of wear.
Is there evidence of internal damage such as a pinched or crushed outer jacket?
If a cord is damaged, tag it out of service and repair or discard it.
Copyright ã1999 Business & Legal Reports, Inc.

27. Other Electrical Hazards and Protective Measures
Damaged insulation on wires
Digging or trenching near buried lines
Overloaded/exposed circuits
Overheated appliances or tools
Flammable materials
Damaged wiring insulation exposes hot wires to potentially combustible materials and may start a fire.
Always contact your local utility companies prior to doing any digging or trenching and have them mark the locations of their wires.
Broken switches or plugs can cause overheating in the circuit.
Overloaded circuits are created when too much electrical current is running through a given electrical system.
Appliances or tools can become overheated if they have an internal electrical problem.
Static electricity can cause discomfort for workers or even start a fire or explosion when around flammable materials.
Make sure flammable materials are properly stored and grounded, especially when chemicals are being dispensed.
Copyright ã1999 Business & Legal Reports, Inc.

28. Safe Work Practices
De-energize electric equipment before inspection or repair (Lock out Tag out)
keeping electric tools properly maintained,
Exercise caution when working near energized lines
Use the correct protective equipment
Watch out for the following:
Tripped circuit breakers or blown fuses
Warm tools, wires, cords, connections, or junction boxes
GFCI that shuts off a circuit
Worn or frayed insulation around wire or connection
Copyright ã1999 Business & Legal Reports, Inc.

29. Guarding of Live Parts
Must guard live parts of electric equipment operating at 50 volts or more against accidental contact by:
Approved cabinets/enclosures, or
Location or permanent partitions making them accessible only to qualified persons, or
Elevation of 8 ft. or more above the floor or working surface
Mark entrances to guarded locations with conspicuous warning signs
